Can space really be never ending?

Question

Well I know who people always say that space never ends but I mean it has to!!! Come on like something could go on forever! If it does end how is that possible? I'm wondernig if it just stops all the sudden you hit a wall like you can't go any further. Please answer with what you think.

Answer 1

i think that it goes on forever, but i think that eventually you'll get to a space where the pressure iss do high that you'll just automatically disappear!!! i don't know

Answer 2

I think it's a loop. You can't reach an end because it just doubles back.

Answer 3

scientists say that universe is expanding and that we do not know how big the universe is and that they have not discover nothing yet.. it can end at some point or it can go on forever and never end.. i think that the universe never ends as strange as it sounds because how it ends?? ok you can have the same question with how cant it end?? ... the surer is that nobody knows and that nobody will know untill they discover it!!.. x*x

Answer 4

Scientists and religious people have their own beliefs on the matter but noone is quite sure but fear not because we can't travel very far in space so it wont be proven anytime soon.

The closest we will get to another planet is alien visitors or UFO's but again not very likely

Answer 5

i think it ends

what comes aftr it?? who knows??

maybe Heaven???

im not sure...

=)

Answer 6

Yes, it can. The human mind cannot conceive eternity and never-ending. Why? Everywhere we turn we encounter boundaries. We see walls everywhere, so naturally our mind tends to think the universe has to have an end . . . it doesn't. That's the hardest thing to understand. The other thing I struggle with is "Self Awareness." What the heck is that. Think about it. We know we exist and where we exist, but we don't remember anything before this life. And yet, our planet has been here for over 4.5 billion years. Weird.

Answer 7

It ends where the 3rd Heaven starts...

Answer 8

Scientists believe that space does end.  Gravity bends the universe back onto itself so that it is not infinite.

Answer 9

Well no one knows for sure but theory says that the universe is infinitely large and just keeps getting larger. I don't believe there is a wall.

Answer 10

There are any number of concepts, but none of them can be scientifically verified, although some who post answers to this type of question present the concepts as though they're etched-in-stone facts.

When talking about either 'what' came before the Big Bang that created our universe, or 'what' lies beyond our universe there's no way that any of the myriad concepts can be invoked without either infinity, an absolute void, or some kind of metaphysical First Cause necessarily entering the picture.

One idea is that our universe has dimensions other than those we're familiar with. How many other dimensions? Six? Eleven? A billion? Assume that there are a hundred additional dimensions. That would leave us right back where we started -- what's beyond those hundred dimensions? The only answer is there must be an infinite number of dimensions.

Another notion is that our universe started when it collided with another universe. Okay, again the original question isn't answered because we're left still hung up on the original question -- what's beyond our universe and the one we collided with?

Then there's the idea that there's some 'mother' universe that spawns other universes. Back to the same question -- what's beyond this 'mother' universe? If there's nothing then it must be infinite.

By calling up Heisenberg's Uncertainty Principle concepts have been developed stipulating that every time a decision is made, like you turn left instead of right at some crossroads, or an atom "decides" to decay, another universe branches off in which the opposite decision is made. Here again the question is 'where' or 'when' did such critical decisions begin? After the Big Bang? That puts us right back at square one -- what was before that?

Answer 11

It would be a fallacy to suppose that space can't be boundless just because we find the notion hard to imagine. I'd say no person who ever studied quantum mechanics found the central notions of that study easy to grasp, but they must eventually accept them because they invariably make correct predictions. Indeed, Richard Feynman was moved to remark, "Anyone who thinks they understand quantum theory doesn't understand quantum theory."

I don't see why it's so ridiculous to think something could go on forever. Most real numbers can't be written down with a finite number of decimal digits, for example. Mathematicians routinely study in an abstract way all manner of infinite spaces--they even study infinite-dimensional spaces. They have yet to find any sort of problem with these spaces. In fact, such spaces are critical in many parts of mathematics.

Now, it should be noted that "boundless" doesn't mean "infinite." Space could be boundless and yet finite. It all depends on its topology. Space may be what is called a closed manifold: compact and yet without boundary. An example would be the surface of a sphere (such as the earth). The surface has no bound, you can go in one direction forever, and yet it's finite.

When I speak of topology, I mean the abstract mathematical notion of topology. The term "compact" also refers to the abstract term, not the term as it is used in daily speech.

I hope this clears up the matter for you somewhat. :D

Answer 12

The universe (and space) are not only stranger than we imagined, they are stranger than we CAN imagine.

Answer 13

the universe is constantly expanding.. meaning there has to be an end, right?  It can't be infinitely large, and still expand.  What's that?  infinity +1?

But what happens at the end of it is beyond me.  I can't even imagine there being nothing.  definitely no wall though, haha

Answer 14

im guessing it fades out to a different color like white. .
